Deathly_hollow, that is completely normal to accept dreams as reality! that is called non-lucid dreams. I have dreams of flying and going to a school ive never seen before with people i see from TV that i call 'friends'. try some kind of other technique that works best for you; deprive yourself of sleep with a few power naps here and there and you'll be fully lucid in no time. you also need to go into habits doing things like you would reality checls for becoming lucid, like "my friends are not real" or something along those lines. try to make it such a big habit that you say it and realize it in your dreams, just the same as realizing that you are lucid.
hope it helps.
